[QUOTE="BountyHunter, post: 1733580, member: 12"] The problem is excess shoulder pushback not FL sizing. Plus it you are using the same dies and adjustments for both guns you need a set of skip ottos die shims to adjust the variance in shoulder pushback needed without having to change fixed die adjustments. The rifles have different headspace. Forget belts, cam over etc and adjust dies for .002. Measure shoulder headspace on both rifles fired brass. Adjust the die to to bump shoulder .002 on the shortest brass and lock die. Now for longer headspace, forget going for cam over, adjust for the.002 shoulder bump using shims. Start with die about 1/8 above shell holder and oy work it down until you get the .002 shoulder bump. On longer brass start with the shim for amount of difference between the 2 head spaces. slowly work down. USe die shims under die to adjust shoulder to .002 on that brass. [/QUOTE]
